Upgrading CPU/RAM on P4QC Mobo

Specs: Windows 7, E6300 Dual Core/Kingston HyperX DDR3 4GB 1333
I have a ASUS P5QC. Currently looking to upgrade my CPU to a Quad Core and RAM to DDR3. Get varying specs when searching on exactly what speed my mobo will support. I'm technical enough to build a sys as I built this one about a yr and a half ago, though 'not' technical enough to setup OC correctly other than using the default 10.5 per thats in the bios options.

Anyways what speed will this mobo support? Do I need to go w/a Quad core 1333 FSB and DDR3 1333 on this mobo? Installed New DDR3 RAM but bios only gives options for 1066, 1600 and 1800 for speeds. 1333 isn't listed, so guesing perhaps it's because the old E6300 Intel CPU is 1066? Ugh sry for being such a 'nooblet' lol but I'm old school when it comes to tech and trying to 'relearn' everything :) Also any suggestions on OC my current cpu which is at 2.8GHZ are greatly appreciated!
TYVM for any help/suggestions!
FYI: Currently looking at Intel Core 2 Quad Q9505 Processor BX80580Q9505 - 2.83GHz, 6MB Cache, 1333MHz FSB, Yorkfield, Quad-Core, Retail, Socket 775 for the CPU.

Below is a link to that board. The overview states: Dual-channel DDR3 1333MHz / DDR2 1066 MHz


You will also find a QVL (Qualified Vendor List) for RAM and a list of supported CPUs.

TYVM! Exactly my point. My DDR3 1333 is showing up as 1066 and the bios doesn't give any options other than 1066, 1600, 1800. Any ideas as to why? Flashed the bios, same prob. That's the same spec info I looked over before purchasing the RAM so a little confused.
So guessing since the only DDR3 1333 on the QVC that's 2MB is Samsung. Ugh Nice. Need to read the QVC I guess next time I purchase a Mobo, although the DDR2 1066 I did have wasn't either and had no issues with it.

Many manufacturers fudge the stated specs and pump up the speed by upping the voltage. What happens when you leave the RAM settings to auto?

I don't run Intel chips so I can't tell you what your optimal RAM speed should be. Normally the reason to buy faster than needed RAM is so you have room to overclock or run tighter settings at the slower speed.

The QVL is not the only RAM that will perform on a particular board. It is RAM that the board manufacturer has tested.

You may want to post a query on the overclocking forum here asking what your optimal RAM speed should be for your CPU.

TYVM for your patience! I think therein lies the problem. More than likely it's because the CPU is 1066. Guessing I'll need to upgrade to the one I posted initially which is 1333 also. Already ck'd and it's on the list of compatible cpu's for this mobo so should be all good. :) TY Again for the reassurance. Thought it was something like that, but seeing the 1600 and 1800 options but no 1333 threw me off a bit. And default is 1066 same as the DDR I had previously.
